It sure did when i was 3 when i watched this show on TV when i fell in love with Cheetara and Pumraya when i was 4. I never knew there was such a fandom until i was 15 with comics in my city’s comic stores like Furrlough, Omaha The Cat Dancer and more to the net and conventions. Even some people have Thundarian fursonalities and even dress up as Thundercats at conventions.
